Survival in Patients With Nonischemic Cardiomyopathy With Preserved vs Reduced Ejection Fraction.

ABSTRACT:

Background

Prior studies suggest similar long-term mortality rates for patients with heart failure (HF) with preserved ejection fraction (HFpEF) vs reduced ejection fraction. However, although coronary heart disease (CHD) is associated with worse prognosis in HF, clinical outcomes are less well characterized for HF without CHD. We investigated the characteristics and 5-year mortality outcomes among patients with HF without significant CHD, stratified by EF.

Methods

Patients with clinical heart failure who underwent coronary angiography at Duke University Medical Center from 1996 through 2009 and had no significant CHD with EF ≤ 40% were compared with patients without significant CHD with EF > 40%. Survival was examined using Kaplan-Meier methods and multivariable Cox
